Hi all.
I wasn't able to determine which topic best suited my query, so I posted it here.
I have several AVI episodes, which is encoded as Xvid + MP3. I'd like to convert them into a DVD friendly format so that I can play it on my DVD player.
And so I tried converting and succeeded in doing the first 3 episodes into one DVD (DVD5)). Great! I simply followed the "AVI to DVD guide" here http://www.doom9.org/mpg/avi2dvdr.htm. This was probably made easy since the encoding was same on all three eps (especially the audio, which is MP3 VBR 48KHz).
Then I ran into problem in the next 3 episodes, where one of the ep had a different sampling rate (32KHz). I should explain myself here that I first start out by joining the AVIs using VirtualDub (as per the guide mentioned above). From there I'd extract out the audio as a WAV, then convert it to AC3. Unfortunately VirtualDub won't allow me to do this for this batch since the audio sampling rate is different (48KHz vs 32Khz). So, instead, I extract out the video and audio separately, joined the video-only files on their own (using VirtualDub), joined the audio-only files on their own, did the conversion (AVI->MPEG-2, WAV->AC3), and finally converge them together using Ifoedit (plus I generate my own celltime.txt containing the frame number of each eps for rudimentary chaptering - don't need menu et al).
PROBLEM - from the second ep/chap the visual and audio is out of sync by a split second (< 1sec)! The audio is delayed! I'm speculating that the problem was in the audio extraction/decoding/encoding part, but unfortuately I have little knowledge of how to deal with it.
So, to explain myself further, here is how I (mis)handled my audio. I extracted out the audio separately from each of the three eps using VDub (select "Full processing mode" then "Save WAV..."). Then I joined the WAV files using a shareware called WAV Joiner. After IfoEditing it resulted in visual/audio sync problem. Next I tried to extract the audio using VDub "Direct stream sopy" then "Save WAV...". I assumed the files were MP3 still so I used Winamp's WAV writeout plug-in to join and convert the files to one WAV file. Again, after IfoEditing visual/audio is still out of sync.
Hope I've provided enough information. Was wondering if anyone can point out what I might be doing wrong to introduce this delay(or the reverse).
Thanks in Advance.
